## Tools

### GDPR Compliance Checker

Scans codebases for potential GDPR compliance issues including personal data patterns and risky code practices.

```bash
# Scan a project directory
python scripts/gdpr_compliance_checker.py /path/to/project

# JSON output for CI/CD integration
python scripts/gdpr_compliance_checker.py . --json --output report.json
```

**Detects:**
- Personal data patterns (email, phone, IP addresses)
- Special category data (health, biometric, religion)
- Financial data (credit cards, IBAN)
- Risky code patterns:
  - Logging personal data
  - Missing consent mechanisms
  - Indefinite data retention
  - Unencrypted sensitive data
  - Disabled deletion functionality

**Output:**
- Compliance score (0-100)
- Risk categorization (critical, high, medium)
- Prioritized recommendations with GDPR article references

---

### DPIA Generator

Generates Data Protection Impact Assessment documentation following Art. 35 requirements.

```bash
# Get input template
python scripts/dpia_generator.py --template > input.json

# Generate DPIA report
python scripts/dpia_generator.py --input input.json --output dpia_report.md
```

**Features:**
- Automatic DPIA threshold assessment
- Risk identification based on processing characteristics
- Legal basis requirements documentation
- Mitigation recommendations
- Markdown report generation

**DPIA Triggers Assessed:**
- Systematic monitoring (Art. 35(3)(c))
- Large-scale special category data (Art. 35(3)(b))
- Automated decision-making (Art. 35(3)(a))
- WP29 high-risk criteria

### Data Subject Rights Tracker

Manages data subject rights requests under GDPR Articles 15-22.

```bash
# Add new request
python scripts/data_subject_rights_tracker.py add \
  --type access --subject "John Doe" --email "[email protected]"

# List all requests
python scripts/data_subject_rights_tracker.py list

# Update status
python scripts/data_subject_rights_tracker.py status --id DSR-202601-0001 --update verified

# Generate compliance report
python scripts/data_subject_rights_tracker.py report --output compliance.json

# Generate response template
python scripts/data_subject_rights_tracker.py template --id DSR-202601-0001
```

**Supported Rights:**

| Right | Article | Deadline |
|-------|---------|----------|
| Access | Art. 15 | 30 days |
| Rectification | Art. 16 | 30 days |

## Workflows

### Workflow 1: New Processing Activity Assessment

```
Step 1: Run compliance checker on codebase
        → python scripts/gdpr_compliance_checker.py /path/to/code

Step 2: Review findings and compliance score
        → Address critical and high issues

Step 3: Determine if DPIA required
        → Check references/dpia_methodology.md threshold criteria

Step 4: If DPIA required, generate assessment
        → python scripts/dpia_generator.py --template > input.json
        → Fill in processing details
        → python scripts/dpia_generator.py --input input.json --output dpia.md

Step 5: Document in records of processing activities
```

### Workflow 2: Data Subject Request Handling

```
Step 1: Log request in tracker
        → python scripts/data_subject_rights_tracker.py add --type [type] ...

Step 2: Verify identity (proportionate measures)
        → python scripts/data_subject_rights_tracker.py status --id [ID] --update verified

Step 3: Gather data from systems
        → python scripts/data_subject_rights_tracker.py status --id [ID] --update in_progress

Step 4: Generate response
        → python scripts/data_subject_rights_tracker.py template --id [ID]

Step 5: Send response and complete
        → python scripts/data_subject_rights_tracker.py status --id [ID] --update completed

Step 6: Monitor compliance
        → python scripts/data_subject_rights_tracker.py report
```

### Workflow 3: German BDSG Compliance Check

```
Step 1: Determine if DPO required
        → 20+ employees processing personal data automatically
        → OR processing requires DPIA
        → OR business involves data transfer/market research

Step 2: If employees involved, review § 26 BDSG
        → Document legal basis for employee data
        → Check works council requirements

Step 3: If video surveillance, comply with § 4 BDSG
        → Install signage
        → Document necessity
        → Limit retention

Step 4: Register DPO with supervisory authority
        → See references/german_bdsg_requirements.md for authority list
```

## Key GDPR Concepts

### Legal Bases (Art. 6)

- **Consent**: Marketing, newsletters, analytics (must be freely given, specific, informed)
- **Contract**: Order fulfillment, service delivery

- **Erasure**: Delete data (with exceptions for legal obligations)
- **Restriction**: Limit processing while issues are resolved
- **Portability**: Provide data in machine-readable format
